Patent CA-2277133-A1 (CA)
Inventor: HOCKADAY ROBERT G
IPC: H01M8/10
Filed: 1998-01-02
Abstract: A miniature fuel cell system uses porous plastic membranes as substrates of fuel cells. A cost effective pore-free electrode or inter electrolyte foil that is permeable only to hydrogen as an ion. The new electrode makes direct alcohol fuel cells efficient. It blocks the poisoning alcohol diffusion through the electrolyte. Compound electrodes are formed by vacuum deposition methods and sluries. That leads to printed circuit designs of small fuel cells systems integrated with rechargeable batteries and electrical power electronics to power applications that are currently powered by batteries. By directly utilizing alcohol fuels the new fuel cells have higher energy per unit mass and higher energy per unit volume. They are more convenient for the energy user, environmentally less harmful and less expensive than conventional batteries.

Patent CA-2281542-A1 (CA)
Inventor: SCHULER JOSEPH
IPC: H04L5/06
Filed: 1998-01-20
Abstract: A communication system (106) receives and codes a plurality of information signals (102-105) according to coding assignments to produce a plurality of coded baseband signals (202-205). From these signals, a simulated composite carrier signal is formed which has all the characteristics of an actual composite carrier signal which would have resulted if the plurality of coded baseband signals had been formed. The simulated composite carrier signal is analyzed to determine its peak-to-average ratio. The communication system (106) selects a different coding assignment for coding the plurality of information signals if, based on the determined peak-to-average ratio and a selection criteria, the coding assignment does not produce the desired results. The communication system (106) selects a different coding assignment until at least one or several desired coding techniques have been identified, ranks the coding techniques and makes a final selection of the coding techniques to meet the peak-to-average ratio requirements.

IPC: H04N21/2343
Filed: 1999-01-19
Abstract: A splicer/transcoder (21) interfaces to an archiver/server of a material with a stream, and to an editor and a switcher (22) with a baseband. During a predetermined period including at least an editing point, the splicer/transcoder (21) performs transcoding.

Abstract: A method, system and apparatus enables carrier- grade network fault monitoring in an unreliable network transport environment. An element manager of the system is adapted for formulating and sending notifications through the unreliable network transport environment, each notification having an unique transmitted notification serial number (TxNSN). A network manager is operatively connected for bi-directional communication with the element manager. The network manager includes a detection mechanism responsive to notifications received from the element manager to detect a missing notification on the basis of the respective TxNSNs of received notifications; and a polling mechanism responsive to detection of a missing notification to send a polling request to the element manager for transmission of a response containing data related to the missing notification. The advantage is simple, easily managed, carrier-grade network fault monitoring without overloading the unreliable network transport environment.
